Spccitcatiov. of Letters Patent.

Application filed February 13, 1911.

iSe it known that i, Jenn M. RUsnr, a citizen. ot the 'United States, residing at the city of ilii.uclel[)iiia in the county of Philadelphia and State ot' Pennsylvanizn have invented a certain new and useful Process of l\ontrolling -i W `ation, of which the followngis a sp tion.

ihe present iiisiention relates to improvements in the e.' tion of tiuid, meaning liquid or unseen: combustibles in a chainbcr, and ils princ l object is to control the temperature ett' the combustion in such a way that intense local heatin f erii'ects may be avoided and the heating e ect properly distributed and, generali stated, it consists in burning the tiuid con'iiuigtible in a chamber and mixing the burnin mass by commingling; the fluid combustible and zur with the hot and newly Aformed products of cornbustion before the escape ot'thcse products ot' romiusstion from the chamber, thereby preventing Yformathm ot' intense local heating' flames and effecting a proper distrito tio-n of heat.

The process may be practised by means of a variety ot' apparatuslmt for the sake of description one` type of apparatus has been chosen from amongi; the many types for the purpose or' illust' oniin the accompanying diiwings in, wl uw Figure i, is a e view with parts broken :ii/'ay of a coal gus bench arranged for the practice at' the pro s ot the invention, and Fig. 2, is a. front view ot' tinl bench shown in Fig. l, with parte broken away.

(tas ,generated in the producer i, is an example ot u iiuid coministible, in connection with i iion of which the Aprocess is bombas, applicable. 'out there are many other Huid munluistibles suii as oil vapors and natural and urtificiai i in connection with the combustion oiz unich the progres is useful.

il". an exemple ot' a chamber in which duid cmnbustihlc inay be bui-ucd in accordanice -Awith the p:- ..oess of the invention but ot' i other forms ot' chamber can be used. f* lacci.' zas tri/nn the chamber 1, reaches the ifl'iainber 9 by wav of the passage 3. 'i71ml-u-1ts of ro :tion escupe from the chamba 2 ,hi-oi h the fines 4. and rear-'u the st rit'. i in pz' through the flues- 5, 1s heated and is er .iarired in part, at (i, under that of burning the pro ucer gas in the c amber 2, inthe present instance to heat the retorta 9.

The foregoing is a description of the ordinary process and apparatus of a gas retort bench which has been chosen from among many processes and apparatus in the art to which the process is applicable and in connection with which it might have beenexplained. The flame formed by the combus tion of the fuel gas with secondary air entering. at 8, produccs'a concentrated combustion and intense local heating effect, This concentrated region of combustion 0r intense local heatingeii'ect is undesirable not only in the case of a coal gas bench but also in the case ofte variety of instances that occur in the arts. With a coal gasbench the result is to heat the retorts unevenly and to overheat ortion of the retorts which is in close proximity with the intense'heatin flame. In accordance with this invention t e burningr fluid combustible. as it is consumed in a chamber, and which is of course at a very high temperature, is stirred, circulated, agitated or distributed so that the formation of intense local heating Home is prevented and a proper distribution of combustion and resulting heat is attained. There are various oxpedients for efl'ceting the described stirring operation. Among these jets have been chosen 'for the sake o explanation and they are illustrated at 12, as extending throng the walls of the chamber' 2, and illscharging generally crosswise ot' or at an inclination see 19. to the direction of travel of the combustible fluid. These jets 12, may be supplied with steam or other appropriate substance through connections as l0, for example with a portion of the air necessary t'or combustion or with a ortion 'of the burninnr mixture itself, or wlth waste prodnets of combustion, each fsuitably impelled through the jet appliance. Openings are shown at 1l, so that the lower jets may operate efcctvely in stirring the burning fluid combustible which is also stirred by the other jets. Since the function of the jets or other stirring;r means is to stir the burning tiuid (.'ombustible as it is consumed the location and arrangement of the stirring means can be changed and varied while still accomplishing the result of eiecting a distribution
